I am using V-carve pro 9 with a design and make 3D project.My design will take over 11 hours to carve. Size of my design is 12"x20". Does anyone know how to carve in 3-4 hour blocks instead of having it carve for 11 hours?

When I knew I had a long running job, I often made a copy of the g code file that I would edit to make a part 1 and part2 file split at a particular line number, so that I could run to ensure I was in control of the machining.

I have since replaced all of the control/driver/motors etc so that I can pause and restart without the risk of losing position. This includes if I lose power.

The new controller allows me to pause or stop the machine code any where, and restart without the risk of losing position. I spent quite a bit of time making sure that I was achieving this functionality.

The new closed loop motors also ensure that I will not skip steps when processing.

If your are running Mach3 you can restart if you know the line number of the G-code where it stops. On the Mach screen there is a "Run From" window. Click on that window. A keypad window will pop up. Type in the G-code number. Hit okay. Then hit "Cycle Start"The G-code will start scrolling from line 1, etc. until it gets to the line # you typed in the "Run From" window, your machine will then start running.

Thanks Joz for the tip. I did reset the scale and it did cut the time down to 8.5 hours. Yes the design is complex. I will have to try to tile the design. I will also explore adding g-code, if I can, to run in separate sessions. I will post the outcome after I try those things.Thanks everyone,Jam
